Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current well stimulation methods, such as hydraulic fracturing, often require multiple steps and equipment configurations, which can be inefficient and limit the flexibility in creating and maintaining fractures for enhanced hydrocarbon flow.
Innovation Solution
A bottomhole assembly (BHA) that combines a jetting tool and a packer to perform hydraulic fracturing using a combination of jetting and annular fluid flow, allowing for various stimulation methods, including simultaneous jetting and fluid pumping, different pressure settings, and sequential fluid injection to optimize fracture creation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hydraulic fracturing is performed using high volume low pressure flow through tubing string, then fracture fluids can be delivered to formation, but the method lacks flexibility in combining jetting and fluid pumping operations
Solution Approach 1:
The patent combines a jetting tool with a packer into a single bottomhole assembly, enabling both jetting and annular fluid pumping operations to be performed simultaneously or sequentially from the same equipment configuration, thereby increasing operational flexibility without requiring multiple separate equipment setups
Solution Approach 2:
The bottomhole assembly is designed to perform multiple functions: jetting through the formation, sealing the annulus with the packer, and pumping stimulation fluids through the annulus. This multi-functional design allows a single equipment configuration to support various stimulation methods including combined jetting and pumping operations
2Productivity
If jetting is performed to perforate formation, then perforation is achieved, but fracture creation requires separate high volume fluid pumping operation
Solution Approach 1:
The patent enables continuous stimulation operations by allowing jetting and annular fluid pumping to occur simultaneously or in seamless sequence from the same bottomhole assembly. The packer seals the annulus to direct fluids efficiently, eliminating downtime between jetting and fracturing operations and maintaining continuous productive action throughout the stimulation process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The BHA enables flexible and efficient well stimulation by allowing jetting and fluid pumping to be continued or adjusted during fracturing, improving fracture creation and maintenance, thereby enhancing hydrocarbon flow and well productivity.
Implementation Method 1
jetting tools that use high pressure nozzles to perforate the formation
Implementation Method 2
A bottomhole assembly may include a jetting tool and a packer to provide hydraulic fracturing using a combination of jetting and annular fluid flow
Implementation Method 3
The fractures are created by introducing a fracturing fluid into the formation at a flow rate which exerts a sufficient pressure on the formation to create and extend fractures therein
Implementation Method 4
Solid fracture proppant materials, such as sand, are commonly suspended in the fracturing fluid so that upon introducing the fracturing fluid into the formation and creating and extending fractures therein, the proppant material is carried into the fractures and deposited therein

AI summary
A bottomhole assembly (BHA) and method for stimulating a well includes setting a packer of the BHA in a wellbore. The BHA includes the packer and a jetting tool coupled to a tubing string. Process fluid is pumped down the tubing string and jetted with the jetting tool to perforate a formation. Stimulation process fluid is pumped down an annulus of the wellbore to fracture the formation.
